2 Claims. l

The invention relates to improvements in illumination and moreparticularly to the novel construction and arrangement of parts in alamp structure. l

Lamps ofV the kind embodying the features of the present inventiongenerally are intended for use on Vanities and dressers so as toilluminate the mirror and the face of a person properly positioned infront of said mirror. The present lamp is particularly designed toeliminate glare and to direct most of the light rays Within ahorizontalV area at an elevation corresponding to the face level of aperson of mean height seated or standing before the vanity or dressermirror so as to provide the greatest illumination at the cheek level. Itis, therefore, an object of the present invention to provide a lamp ofthe kind described With a pedestal or standard ofv suicient height to`locate the source of illumination thereon at a height relative to theobject upon which the lamp is positioned so as to cause the light raysemitted therefrom to be directed for the greater part within a planarareeJ corresponding to such height.

Table and vanity lamps of the kind having a harp embracing the lightbulb therein for supporting a shade thereover, frequently are expensiveto manufacture and difcult to assemble. It is therefore another objectof the present invention to provide such a lamp with an easily removableharp which may be easily and quickly attached and firmly retained inplace.

Another object of the invention is to provide a lamp ol the kinddisclosed with a dilusion and deflecting disk suitably shaped so as todirect light rays` converging thereon upwardly and outwardly through alamp shade supported thereabove.

Another object of the invention is to provide a lamp of the characterdescribed which may be easily and quickly disassembled so as to reduceits overall height and thereby enable such a lamp to be packed within arelatively small shipping container.

Another object of the invention is to provide a dresser or vanity lampwhich is not expensive to manufacture but is easy to assemble and highlyeii'lcient in use.

Other and further objects of the present invention will be apparent fromthe following description and claims and are illustrated in theaccompanying drawing which illustrates a preferred embodiment and theprinciples thereof and which is considered to be the best modecontempiatedf for applying, that principle. Other embodiments of theinvention embodying the same or equivalent principles may be used andstructural` changes may be made as desired by those skilled in the artwithout departing from the: spirit of.` the present invention and thepurview of! the appended claims.

Inthe drawings Fig. 1 is a view: illustrating a pair of lamps ernbcdyingfeatures of the present invention mounted upon a dresser or vanity.

Fig. 2 is anv enlarged longitudinal sectional detail View of a portionof one of the lamps shown in Fig. 1:

Fig. 3 is a horizontal sectional detail View taken online 3-3" of Fig.2';

Fig. 4 is a view showing the harp.

As best shown in the drawing, the lamp of the present invention is of akind adapted to be arranged on adresser or vanity and it includes abase. lil, and a. standard I2 having a conventional socket. i3, at, its.upper end, to receive a conventional electric. light b ulb. I4. Thestandard l2 is of such height as to locatel the light bulb I4 at alevel. corresponding to the cheek level of a person of mean averageheight standing or seated before the, dresserV orvanity on which thelamp is, mounted.. The location of the light bulbv at this leve1 isadvantageous because the light rays emitted therefrom are vdirected forthe greater part within an area., corresponding to the cheek level ofsuch person: and to the image thereof in a mirror HiA or otherreiiecting surface associated vwith thedresser or vanity. The lamp alsois constructed; so as to facilitate deflection of light rays, into thedesired area with the minimum amount or, theY light rays being reflectedupon the highly-polished top. surface lr6 of the dresser orvanity.

As best showny in Fig. 2, thek bulb socket I3v is rmly attached totheupper end of the usual tub.. ing lt extended? through the standard l2for conducting an electric conductor I8 to the socket. The socket F3 iszsuitably enclosed within a cupshaped husk er cover i9 which, in thepresent instance, is suitably contracted at its bottom, as at 2|, so asto be firmly secured to the standard l2j and it has the upper margin ofits circular Wall offset outwardly, to provide an annular internalshoulder 22, and then upwardly, as at 23, to provide a peripheral lip ormargin.

The flange 22 and lip 23 provide a support upon which is mounted a lightdiffusing and deecting translucent disk 24 which, in the presentinstance,

consists of aring shaped member suitably dished and inverted so that itssmooth upper surface 25 is inclined downwardly outwardly towards itsperipheral edge 26. The disk 24 has a central opening 27 of a sizecorresponding substantially to the area of the open end of the husk l 9,which opening receives snugly therein a circular' flange 28 formed on anannulus 29 which projects downwardly into the dished bottom region ofthe disk 24. The annulus 29 has an outside diameter substantiallycorresponding to the inside diameter of the lip 2,3 so that when thedisk 24 is mounted in place over the husk i 9, the annulus 29 seatssnugly within the lip 23 and rests firmly upon the annular shoulder 22.It is submitted that the disk 24 is mounted in such manner as to beeasily mounted or removed and that when mounted .it is rmly held inplace against dislodgment.

The husk r socket cover I9 is provided with a pair of diametricallyopposed tubular receptacle iittings 3| which are rmly secured, as bywelding or soldering, to the inside surface of the cylindrical wallportion of said husk and are disposed to locate their open upper ends 32substantially in the plane of the annular shoulder 22. The receptacles3| are each adapted to receive one leg 33 of a substantially U-shapedharp 34 which is mounted for easy insertion and removal around the lightbulb I4 carried by the socket l It should be observed at this time thatthe harp 34 is shaped to conform substantially to the contour of thelight bulb I4 so as to thereby make it impossible for a light bulbhaving a contour materially different than that illustrated to beinserted in the socket i3.

It is submitted that the lamp structure of the instant disclosure isparticularly designed to cause the greatest illumination within aselected area and that the illumination directed into such area bediiused or deected so as to produce a soft light. As a consequence,thelight bulb i4 preferably has two filaments, one of suicient wattageto provide the necessary illumination under conditions of use and theother to provide a lesser amount of light when the lamps are to be usedfor general illumination. It is for this reason that the harp 34 isdesignedto prevent the substitution of larger or smaller light bulbs ofmore or less wattage so as to thereby insure maximum efficiency in theuse of the lamp.

The harp 34 includes a stem 35 rmly secured on the medial portionthereof to provide a support for a lamp shade 36 of any conventionalconstruction -but preferably of sufficient depth to locate the loweredge 3l thereof below the plane of the peripheral margin 26 of the disk24. This cooperative relationship established between the disk 24 andlamp shade 36 is such as will prevent direct light rays from strikingthe supporting surface I6. Such light rays as are directed downwardlyfrom the light bulb i4 are deflected by the disk 24 upwardly andoutwardly through the lamp shade 36 into the planular area intended forgreatest illumination. Diffused light rays passing through thetranslucent disk 24 provide the minimum amount of illumination necessaryfor normal Vision in the area below the area of greatest illumination.

Inadvertent or easy removal of the harp -34 from the husk or socketcover` I9 is prevented by 70 .4 initially forming the harp 34 with itsleg portions 93 spread apart a distance greater than the distancebetween the diametrically opposed receptacles 3l, as illustrated in Fig.4, so that said leg portions must be squeezed or otherwise urged towardsone another during initial insertion thereof into said receptacles. Theinherent resiliency of the harp 34, tending to move the leg portionsapart, will provide suiiicient friction in the harp mounting to resistunintended movement of said harp outwardly from the receptacles 3|.

Although a preferred form of construction has been illustrated in theaccompanying drawing and described herein and the lamps have been shownas associated with an exemplary form of dresser or vanity, it should beunderstood that improved lamps may be employed in connection with otherarticles of furniture than that shown and that the structure thereof mayembody a wide variety of modifications in detail construction withoutdeparting from the spirit of the invention or the scope of the appendedclaims.

We claim:

1. A lamp xture comprising, in combination, a socket to receive a lampbulb, a, cup-like shell encompassing said socket, an annular externalflange on the upper rim edge of said shell having a circumferentialupstanding lip on its peripheral edge, an annulus seated on said flange,a shoulder formed on the upper surface of said annulus adapting theannulus to receive and support a light-diffusing disc, a pair ofdiametrically opposed tubular receptacles integral with said shell, andan inverted substantially U-shaped member having parallel leg portionsremovably received in said receptacle.

2. A lamp xture comprising, in combination, a socket to receive a lampbulb, a cup-like shell encompassing said socket, an annular externalflange on the upper rim edge of said shell, an annulus seated on saidflange, a shoulder formed on the upper surface of said annulus adaptingthe annulus to receive and support a light-diifusing disc, a pair ofdiametrically opposed tubular receptacles integral with said shell, andan inverted substantially U-shaped member having parallel leg portionsremovably received in said receptacle.
